My Turbo Upgrade What Power Should It Make?

[Guilt-Toy]

Have upgraded more bits n pieces.

Got a Plazmaman Plenum and a 600x300x100 Intercooler

Q45 AFM (Huge sucker)

GCG said that turbo should come on boost at 3500 rpm - does anyone here have a RB30DET with the GT3540 ?

[Butters]

I have an SR20 with gt3540R with .82 rear makes 1 bar about 4600

obviously this not an rb30 but with 2 more cyclinders and 1 litre more then my sr20 you would expect it to spool 1 bar a good 1000 rpm earlier.

I have a 35/40 with .82 exh on my RB30det, in 4th gear it will start making some boost at around 2600-2800rpm, with full boost (20psi) hitting at around 3200-3400rpm.

Nice... Thats what i wanted to hear =) your using standard manifold though ?? Im using a cheapo stainless steel top mount. Will that make it come on later ?

[MattSR]

It will make it come on earlier

Wouldnt you expect the longer runners on the high mount compared to the short ones on the stocker to make the boost come on a bit later if anything?

Thats what i was thinking. Wouldnt it be more laggy because the air has a longer way to travel ?

It wouldnt be laggier, if anything it would drop backpressure, increasing the top end capabilites

[Guilt-Toy]

can anyone else shed some light on this ?

Because the next stage for mods would be Forgies / Cams / Rods and much more boost.

This turbo has the .82 housing so its not the 700hp version of the GT3540 right ? wouldnt the 1.06 be the 700hp version ?

<{POST_SNAPBACK}>

^^^^This is what GCG told me when buying my turbo. 700hp with the 1.06 and about 600hp with the 0.82. I would have thought that a 0.82 on a 3 litre would have been ok, if not under spec'd. I dont have first hand experience with 3 litres though; SK does.

i have a 1.06 on a rb27

and i makeing boost around 3 and full boost by 4

but i dont have a 7k redline

ive got 8.8k

if i had my way again and i will in a few month it will be getting upgraded to t04z .71 same resonse but larger top end

[Guilt-Toy]

would a blow off valve be required for this setup ?

From what ive seen and been told the difference in spool is hardly noticable.

why wouldn't it?

Got a couple of pics since gettin it all going! Sounds great and after some MAJOR issues with crappy made ex manifolds its all up and running.

Should get it tuned properly in the next couple of weeks.
